VESSEL TRAFFIC SERVICE VTS INSTRUCTION MANUAL JRC Code : H-7ZPKP0001 PRECAUTIONS BEFORE OPERATION Cautions for high voltage High voltages from hundreds volts to tens of thousands volts are to be applied to the electronic equipment such radio and radar devices. You do not face any danger during normal operation, but sufficient cares are required for maintenance, inspection and adjustment of their internal components. (Maintenance, check-up and adjustment of the inside of the equipment are prohibited except by maintenance specialists.) High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from electric shock, but even voltages of hundred volts may sometimes lead to a death from electric shock. To prevent such an accident, make it a rule to turn off the power switch, discharge capacitors with a wire surely earthed on an end make sure that internal parts are no longer charged before you touch any parts inside these devices. At the time, wearing dry cotton gloves ensures you further to prevent such danger. It is also a necessary caution to put one of your hands in the pocket and not to use your both hands at the same time. It is also important to select a stable foothold always to prevent additional injuries once you were shocked by electricity. If you were injured from electric shock, disinfect the burn sufficiently and get it taken care of promptly. What to do in case of electric shock When finding a victim of electric shock, turn off the power source and earth the circuit immediately. If it is impossible to turn off the circuit, move the victim away promptly using insulators such as dry wood plate and cloth without touching the victim directly. In case of electric shock, breathing may stop suddenly if current flows to the respiration center in the brain. If the shock is not so strong, artificial respiration may recover breathing. When shocked by electricity, the victim will come to look very bad with weak pulse or without beating, resulting in unconsciousness and rigidity. In this case, it is necessary to perform an emergency measure immediately. FIRST-AID TREATMENTS First-aid treatments As far as the victim of electric shock is not in dangerous condition, do not move him and practice artificial respiration on him immediately. Once started, it should be continued rhythmically.
(1) Do not touch the victim confusedly as a result of the accident, but the rescuer may also get an electric shock.
(2) Turn off the power source calmly and move the victim away quietly from the electric line.
(3) Call a physician or ambulance immediately or ask someone to call a doctor.
(4) Lay the victim on this back and loosen his necktie, clothes, belt, etc.
(5) a. Examine the victims pulse.
(6) Open the victims mouth and take out artificial teeth, cigarette or chewing gum if any. Keep his mouth open, stretch his tongue and insert a towel or the like in his mouth to prevent the tongue from suffocating. (If it is hard to open his mouth due to set teeth, open it with a screwdriver and insert a towel in this mouth.) b. Examine his heartbeat bringing your ear close to his heart. c. Examine his breathing bringing the back of your hand or your face close to his face. d. Check the size of the pupils of his eyes.
(7) Then, wipe his mouth so that foaming mucus does not accumulate inside. When pulse is beating but breathing has stopped
(Mouth-to-mouth respiration) Fig. 1 neck.)
(1) Tilt the victims head back as far as this face looks back. (A pillow may be inserted his
(2) Push his jaw upward to open his throat wide (to spread his airway).
(3) Pinch the victims nostrils and take a deep breath, block his mouth completely with yours and blow into his mouth strongly. Take a deep breath again and blow into his mouth. Continue this 10 to 15 times a minutes (blocking his nostrils).
(4) Carefully watch that he has recovered his natural breathing and atop practicing artificial respiration. If it is difficult to open the victims mouth, insert a rubber or vinyl tube into one of his nostrils and blow into it blocking the other nostril and his mouth completely.
(6) When the victim recovers consciousness, he may try to stand up suddenly, but let him lie calmly and serve him with a cup of hot coffee or tea and keep him warm and quiet. (Never give him alcoholic drinks.)
(5) Method of mouth-to-mouth respiration by raising head
(1) Raise the victims head. Support his forehead with one of your hand and his neck with the other hand. 1 When you tilt his head backward, the victim, in most cases, opens his mouth to the air. This makes mouth-to mouth respiration easy.
(2) Cover his mouth as widely as possible with yours and press your cheek against his nose 2 or, pinch his nostrils with your fingers to prevent air from leaking. 3
(3) Blow into his lungs. Continue blowing into his mouth until his breast swells. Blow into his mouth as quickly as possible for the first 10 times. Fig. 1 Mouth-to mouth respiration When both pulse and breathing have stopped Perform the (Cardiac massage) Fig. 2 and (Mouth-to-mouth respiration) Fig. 1 When no pulse has come not to be felt, his pupils are open and no heartbeat is heard, cardiac arrest is supposed to have occurred and artificial respiration must be performed.
(1) Place your both hands, one hand on the other, on the lower one third area of his breastbone and compress his breast with your elbows applying your weight on his breast so that it is dented about 2cm (Repeat compressing his breast 50 times or so a minutes). (Cardiac massage) In case of one rescuer, Repeat cardiac massages about 15 times and blow into his mouth 2 times quickly, and repeat this combination. In case of two rescuers, One person repeats cardiac massages 15 times while the other person blow into his mouth twice, and they shall repeat this combination. (Perform the cardiac massage and mouth-to-mouth respiration)
(3) Examine his pupils and his pulse sometimes. When the both have returned to normal, stop the artificial respiration, serve him with a cup of hot coffee or tea and keep him warm and calm while watching him carefully. Commit the victim to a medical specialist depending on his condition. (Never give him alcoholic drinks.) To let him recover from the mental shock, it is necessary for persons concerned to understand his situations and the necessary treatment.

PRECAUTIONS DANGER Never carry out internal inspection or repair work of the equipment by users. Inspection or repair work by uncertified personnel may result in fire hazard or electrocution. For inspection and repair work of equipment components, consult with our branch office, branch shop, sales office, or our distributor in your district. When conducting maintenance, make sure to turn the main power off. Failure to comply may result in electrocution. Turn off the main power before cleaning the equipment. Especially when a rectifier is used, make sure to turn it off since voltage is still outputted from the rectifier even after the indicator and the radar are turned off. Failure to comply may result in equipment failure, or death or serious injury due to electric shock. When conducting maintenance work on the scanner, make sure to turn its main power off. Failure to comply may result in electrocution or injuries. Make sure to turn off the scanner safety switch. Failure to comply may result in injuries caused by physical contact with the rotating scanner. Do not touch the radiator. Even if the power is turned off, the radiator may be rotated by the wind.
- iii -
WARNING Never directly touch the internal components of the scanner or indicator. Direct contact with these high-voltage components may cause electrocution. For maintenance, inspection, or adjustment of equipment components, consult with our branch office, branch shop, sales office, or our distributor in your district. To contact our sales department, branch offices, branch shops, and sales offices:
Please refer to the "Office List" at the end of the document. Do not get close to the radiant section of the scanner. It is a rotating part, and it may cause injuries if it suddenly starts rotating and consequently hits the body. It is recommended that the radiant section be installed at a high place such as on the roof of the wheelhouse, on the flying bridge, on the trestle, or on the radar mast so that no one can get close to it. When any work must be done on the scanner, make sure to turn the safety switch off. Microwave radiation level:
Keep out from a distance closer than that specified below for each type of scanner when it is transmitting. Being within the specified distance from the center of the front face of the scanner may cause microwave exposure which could result in injuries (especially of the eyes). NKE-600-2F2T/2254 (radiation levels: 10 W/m2): 0.6 m NKE-600-2C1T (radiation levels: 10 W/m2): 1.1 m NKE-600-2C1T (radiation levels: 100 W/m2): 25 cm Make sure to install the scanner at a place higher than human height. Direct exposure to electromagnetic waves at close range will have adverse effects on the human body.
- iv -
WARNING Do not change MBS Level/Area unless absolutely necessary. Incorrect adjustment will result in deletion of nearby target images and thus collisions may occur resulting in death or serious injuries. When cleaning the display screen, do not wipe it too strongly with a dry cloth. Also, do not use gasoline or thinner to clean the screen. Failure to comply will result in damage to the screen surface. Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. When it is necessary to get close to the scanner for maintenance or inspection purposes, make sure to turn the indicator power switch to "OFF" or "STBY."
Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. When conducting maintenance work, make sure to turn off the power and unplug the power connector J1 of the radar process unit so that the power supply to the equipment is completely cut off. Some equipment components can carry electrical current even after the power switch is turned off, and conducting maintenance work without unplugging the power connector may result in electrocution, equipment failure, or accidents. When disposing of used lithium batteries, be sure to insulate the batteries by attaching a piece of adhesive tape on the + and - terminals. Failure to comply may cause heat generation, explosion, or fire when the batteries get shorted out.
- v -
CAUTION A malfunction may occur if the power is instantaneously interrupted during operation of the radar. In this case, the power should be turned on again. Normally, use the automatic tune mode. Use the manual tune mode only when best tuning is not possible in the automatic tune mode due to deterioration of magnetron. If the gain is too high, unnecessary signals including receiver noise and false video increase resulting in reduction of visibility of targets. On the contrary, if the gain is too low, targets including ships and dangerous objects may not be clearly indicated. When using the sea clutter suppression function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the sea clutter suppression function, make sure to choose the most appropriate image noise suppression level. When using the rain / snow clutter suppression function, never set the suppression level too high canceling out all image noises from the rain or snow at the close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the rain / snow clutter suppression function, make sure to choose the most appropriate image noise suppression level.
- vi -
CAUTION Use the radar only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on the radar display may cause accidents such as collisions or running aground. Use target tracking function only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on tracking target information may cause accidents. Tracking target information such as vector, target numerical data, and alarms may contain some errors. Also, targets that are not detected by the radar cannot be acquired or tracked. In setting an automatic acquisition zone, it is necessary to adjust the gain, sea clutter suppression and rain clutter suppression to ensure that target echoes are displayed in the optimum conditions. No automatic acquisition zone alarms will be issued for targets undetected by the radar, and this may cause accidents such as collisions. Target Tracking Function Test is provided to test if the target tracking function is operating normally. Thus, do not use the function except when you test the target tracking function. In particular, if the operation test mode is used during operation, pseudo targets appear on the radar display and they are confused with actual targets. Do not use the mode during navigation. Otherwise, an accident may result.
- vii -
CAUTION If a great value is set as a condition for deciding targets as identical, a tracking target near an AIS target is regarded as identical to the AIS target and it may not be displayed any more. For example, when a pilot boat (which is a small target not being tracked) equipped with an AIS function approaches a cargo ship as a tracking target not equipped with an AIS function, the tracking target symbol of the cargo ship may not be displayed any more. These alarms may include some errors depending on the target tracking conditions. Making the final decision based only on the alarm may cause accidents such as collisions. Any adjustments must be made by specialized service personnel. Incorrect settings may result in unstable operation. Do not make any adjustments during operation. Failure to comply may result in adverse effects on the radar function which may lead to accidents or equipment failure. Optimal values have been set for Video Level and Vector Constant; therefore, never change their values unless absolutely necessary. Failure to comply may result in accidents that would lower target tracking performance. Do not change the quantization level settings unless absolutely necessary. If set at an inappropriate value, the target acquisition or target tracking function deteriorates, and this may lead to accidents. Any adjustments must be made by specialized service personnel. Failure to comply may result in accidents or equipment failure.
- viii -
CAUTION Make sure to shut off the main power before replacing parts. Failure to comply may result in electrocution or equipment failure. When replacing magnetrons, make sure to shut off the main power and let the equipment stand for more than 5 minutes to discharge the high-voltage circuit. Failure to comply may result in electrocution. Make sure to take off your watch when your hand must get close to the magnetron. Failure to comply may result in damage to the watch since the magnetron is a strong magnet. Make sure that two or more staff member work together when replacing the LCD. If only one person attempts to replace the LCD, he/she may drop it and become injured. Do not directly touch the inverter circuit of the LCD display with a bare hand since high voltage temporarily remains in the circuit even after the main power is shut off. Failure to comply may result in electrocution.

(High performance edition) Tracks of up to 20 target ships can be stored with a maximum of 1,500 points for each of them, and displayed distinguished by using 7 different colors. Note: ARPA/ATA Process Unit must be fitted on ships compliant to IMO. Overlay of Radar Images, Coastlines, and Track As well as operator-created NAV lines, the data of coastlines, objects such as buoys, and target tracks / AIS tracks, which is stored on the memory card can be superimpose-displayed with radar images and radar trails in all display modes including the head-up mode. Creation / display of marks and lines (up to 2000 items). Use of the optional plotter function enables the own track display distinguished by using 7 different colors, creation of marks and lines (up to 20000 items) and the settings of waypoints / courses. Easy Operation with GUI All the radar functions can be easily controlled by simply using the trackball and 2 switches to operate the buttons shown on the radar display. Improved Day / Night Mode Five types of background colors are available in Day / Dusk / Night mode. Each background color can be reproduced to be suited for the users operating environment by simple key operation. The radar echoes and a variety of graphics can also be represented in different colors, ensuring easy-to-see displays. 1-2 Self-diagnostic Program Incorporated The Self-diagnostic program always monitors all the functions of the system. If any function deteriorates, an alarm message will appear on the radar display and an alarm sounds at the same time. Even when the system is operating, the functionality test can be carried out. (except on some functions) Performance Monitor (Option) The radar performance (transmitted output power and receiving sensitivity) can appear on the radar display. Note: Performance monitor must be fitted on ships compliant to IMO. Easy Interswitch Operation (Option) If an interswitch unit (option) is connected, up to four JPL-600-MK2 radars can be switched over by performing simple operation.

Do not put anything on the operation panel. If you put anything hot on it, it may be deformed.
Do not give any impact to the operation panel, trackball, or controls. Otherwise, any failure or damage may result. POWER ON AND START THE SYSTEM OBSERVE AND ADJUST VIDEO ACQUIRE AND MEASURE DATA END THE OPERATION AND STOP THE SYSTEM Each operation is described in detail below. 3-1 3.1 Operation Flow
3.1.1 Power ON and Start the System CAUTION A malfunction may occur if the power is instantaneously interrupted during operation of the radar. In this case, the power should be turned on again. 3 Attention
Wait for about 2 seconds before turning on the power again.
Immediately after the radar is installed, at start of the system after it has not been used for a long time, or after the magnetron is replaced, preheat the equipment in the standby state for 20 to 30 minutes before setting it into the transmit state.
If the preheating time is short, the magnetron causes sparks, resulting in its unstable oscillation. Start transmission on a short-pulse range and change the range to the longer pulse ranges in turn. If the transmission is unstable in the meantime, immediately place the system back into the standby state and maintain it in the standby state for 5 to 10 minutes before restarting the operation. Repeat these steps until the operation is stabilized. 3-2 Procedures 1 Be sure that the commercial power is being supplied. 2 Press the [STBY] key. The system is turned on, and the preheating time is displayed. Preheat is indicated upper left of the display. 3 Wait until the preheating time is over. When the preheating time is over, the preheating time screen disappears, and Preheat upper left of the display changes to Standby . 4 Press the [TX / PRF] key. The radar will start transmission and the antenna will start rotating. Standby upper left of the display changes to Transmit . Note: The radar does not start transmission if you Press the [TX / PRF] key while Preheat is indicated. 3.1.2 Observe and Adjust Video Procedures 1 Press the [RANGE+] key or [RANGE-] key to set the range to the scale required for target observation. 2 Turn the dials [GAIN / PL], [AUTO-SEA], and [AUTO-RAIN] to obtain the clearest targets. Refer to
[GAIN/PL]3-7P
[AUTO-SEA]3-7P
[AUTO-RAIN]3-9P for how to use each dial. For how to adjust video, see Chapter 3.2. 3.1.3 Acquire and Measure Data For details on how to acquire data and measure, see Section 4 "Measurement of range and bearing."
3.1.4 Display and Measure with Reference to CCRP The radar video, range, bearing, Target Tracking and AIS data display etc... are displayed with reference to CCRP (Consistent Common Reference Point). If scanner is switched, these data are measured from CCRP. If some kind of functions set scanner position to outside of the PPI range, these data except Target Tracking and AIS data are displayed with reference to scanner position. For how to setting CCRP, see the section 7.1.9. 3-3 3.1 Operation Flow
3.1.5 End the Operation and Stop the System 1 Press the [STBY] key. The radar will stop transmission and the antenna will stop rotating. Transmit upper left of the display changes to Standby . Maintain the standby state if radar observation is restarted in a relatively short time. Only pressing the [TX / PRF] key starts observation. 2 Press the [STBY] key and the [TX / PRF] key together. The system will be turned off. 3 Exit 3-4 3.2 OBSERVE AND ADJUST VIDEO 3.2.1 Adjust Monitor Brilliance [BRILL]
Procedures 1 Obtain the best-to-see display with optimum brilliance by turning the
[BRILL] dial at the lower right of the LCD monitor. Turning the [BRILL] dial clockwise increases the brilliance of the entire display. Conversely, turning the [BRILL] dial counterclockwise decreases the brilliance of the entire display. In consideration of the ambient brightness, adjust display brilliance that is high enough to easily observe the radar display but does not glare. 3.2.2 Change Observation Range [RANGE + / - ]
Procedures 1 When increasing the observation range, press the [RANGE+] key. Increasing the observation range will enable a wider range to be observed. However, a video image is small and the ability to detect targets near own ship decreases. Therefore, when observing the vicinity of own ship, use the smaller observation range. 2 When decreasing the observation range, press the [RANGE-] key. Decreasing the observation range will enable the vicinity of own ship to be enlarged. However, caution must be taken because video images of the area beyond the observation range cannot be displayed. 3-5 3.2.3 Tune 3.2 Observe and Adjust Video
CAUTION Normally, use the automatic tune mode. Use the manual tune mode only when best tuning is not possible in the automatic tune mode due to deterioration of magnetron. 3 This radar system provides the automatic tune mode and the manual tune mode. The automatic tune mode automatically adjusts the tuning of the transmitting frequency and the receiving frequency, and the manual tune mode enables tuning to be adjusted by using the dial located on the operation unit. The tune mode currently being used is displayed in the tune mode switching (lower left of the display on page 2-18). Procedures When using the automatic tune mode Procedures 1 Put the cursor on the tune mode switching (lower left of the display on page 2-18) and press the [ENT] key. The automatic tune mode is selected and AUTO is displayed in the tune mode field. Tune adjustment is automatically conducted. Tune is adjusted at the start of transmission, at the change of the range or pulse length. Tune adjustment is completed within several seconds. When using the manual tune mode 1 Put the cursor on the tune mode switching (lower left of the display on page 2-18) and press the [ENT] key to set the manual tune mode. The automatic tune mode is cancelled, and MAN is displayed in the tune mode field. 2 Press the [MULTI] dial to set the ( Tune ) mode. Tune is displayed in the multi-dial mode (lower left of the display on page 2-3). 3 Turn the [MULTI] dial to adjust tune. Make adjustments so that the tuning indication (upper left of the display on page 2-2) indicates the maximum. 3-6 3.2.4 Adjust Gain [GAIN / PL]
CAUTION If the gain is too high, unnecessary signals including receiver noise and false video increase resulting in reduction of visibility of targets. On the contrary, if the gain is too low, targets including ships and dangerous objects may not be clearly indicated. Procedures 1 Adjust noise of the display by turning the [GAIN / PL] dial until targets can be easily observed. Turning [GAIN / PL] dial clockwise increases gain. Turning [GAIN / PL] dial counterclockwise decreases gain. By increasing receiving gain, the range to observe radar video is widened. To observe densely crowded targets or short-range targets, reducing the receiving gain will enable the targets to be easily observed. 3.2.5 Suppress Sea Clutter [AUTO-SEA]
CAUTION When using the sea clutter suppression function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the sea clutter suppression function, make sure to choose the most appropriate image noise suppression level. 3-7 3.2 Observe and Adjust Video
Using the manual sea clutter suppression mode Procedures 1 Adjust the sea clutter returns of the display by turning the
[AUTO-SEA] dial until targets can be easily observed. Turning [AUTO-SEA] dial clockwise suppresses sea clutter returns. Turning [AUTO-SEA] dial counterclockwise intensifies sea clutter returns. The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving gain on a short range. Turning the [AUTO-SEA] dial clockwise heightens the effect of sea clutter suppression. However, be careful that excessive suppression causes low signal-strength targets such as buoys and boats to disappear from the radar display. 3 Using the automatic sea clutter suppression mode The sea clutter suppression in accordance with the intensity of sea clutter is possible. Use this mode when the sea clutter's intensity differs according to directional orientation. Procedures 1 Press the [AUTO-SEA] dial. The automatic sea clutter suppression mode is selected, and AUTO is displayed in sea clutter suppression (Sea) mode switching (lower left of the display on page 2-18). 2 Make adjustments by turning the [AUTO-SEA] dial. Even when the automatic sea clutter suppression mode is selected, turning the
[AUTO-SEA] dial can make fine adjustments manually. Note: When the automatic sea clutter suppression mode is selected, the automatic rain/snow clutter suppression mode is switched to the manual mode. To select both the sea clutter suppression function and the rain/snow clutter suppression function in the automatic mode, use the automatic rain/snow clutter suppression mode. Cancellation 1 Press the [AUTO-SEA] dial. The automatic sea clutter suppression mode is cancelled, and MAN is displayed in the sea clutter suppression (Sea) mode field. 3-8 3.2.6 Suppress Rain / Snow Clutter [AUTO-RAIN]
CAUTION When using the rain / snow clutter suppression function, never set the suppression level too high canceling out all image noises from the rain or snow at the close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the rain / snow clutter suppression function, make sure to choose the most appropriate image noise suppression level. Using the manual rain / snow clutter suppression mode Procedures 1 Adjust the rain / snow clutter returns of the display by turning the
[AUTO-RAIN] dial until targets can be easily observed. Turning [AUTO-RAIN] dial clockwise suppresses rain / snow clutter returns. Turning [AUTO-RAIN] dial counterclockwise intensifies rain / snow clutter returns. When the [AUTO-RAIN] dial is turned clockwise, the rain / snow clutter suppression function suppresses rain / snow clutter returns and gets targets hidden by rain / snow clutter returns to appear of the display. However, be careful that excessive suppression may cause small targets to be overlooked. Since the rain / snow clutter suppression function also has the effect of suppressing sea clutter, the suppression efficiency improves when the
[AUTO-RAIN] dial is used with the [AUTO-SEA] dial. In general, turn the
[AUTO-RAIN] dial fully to the left. 3-9 3.2 Observe and Adjust Video
Using the automatic rain / snow clutter suppression mode The rain / snow clutter suppression in accordance with the intensity of rain / snow clutter is possible. Use this mode when the rain / snow clutter's intensity differs according to directional orientation. Procedures 1 Press the [AUTO-RAIN] dial. The automatic rain / snow clutter suppression mode is selected, and AUTO is displayed in the sea clutter suppression (Sea) mode switching and the rain / snow clutter suppression (Rain) mode switching ( lower left on the display and on page 2-18) 2 Make adjustments by turning the [AUTO-RAIN] dial and the
[AUTO-SEA] dial. Even when the automatic rain / snow clutter suppression mode is selected, turning the
[AUTO-RAIN] dial and the [AUTO-SEA] dial can make fine adjustments manually. 3 Note: When the automatic rain / snow clutter suppression mode is selected, the automatic sea clutter suppression mode is also activated. It is not possible to set only the rain / snow clutter suppression function to the automatic mode. 1 Press the [RAIN] dial. Cancellation The automatic rain / snow clutter suppression mode is cancelled, and AUTO is changed to MAN in the sea clutter suppression (Sea) mode field and the rain /
snow clutter suppression (Rain) mode field. 3.2.7 Reset Alarm Buzzer [ALARM ACK]

Fixed targets do not flicker and are easily identified on the chart, and the true bearing of a target can easily be read out. The video is displayed so that the ships heading line points to the zenith of the PPI (0 on bearing scale). Since targets are displayed in their directions relative to the ships heading line, the operator can view the video in the same field of view as in operating the ship at sea. This mode is suitable for watching over other ships. Course-up Mode [C Up]
By setting the course-up mode, own ship's course is fixed so that it is located on the zenith of the display (0 on bearing scale). In the same way as in the North-up mode, fixed targets do not flicker, and are stabilized even if the ship is yawing. The bearing of the heading line varies by the same shift of own ships course.

: Use this mode to monitor a relatively short range, for example, bays and coasts where many boats and ships are running. (Importance is attached to resolution.)
: Use this mode to monitor a relatively long range.
(Importance is attached to long-range gain.)
: Use this mode to detect small targets hidden by sea clutter returns.
(Importance is attached to sea clutter suppression, and gain to moving targets lowers.)
: Use this mode when many rain / snow clutter returns or sea clutter returns are detected in stormy weather. (Importance is attached to rain / snow clutter and sea clutter suppression, and gain slightly lowers.)
: Use this mode when only a few rain / snow clutter returns or sea clutter returns are detected.
: Use this mode when sea clutter is not strong but rain / snow clutter is strong.
(Importance is attached to rain / snow clutter suppression, and gain slightly lowers.)
: Use this mode to detect flocks of sea birds.
: Use this mode to monitor utmost distances in the broad ocean.
: Use this mode to detect small targets like radio buoys in areas outside the sea clutter area. (This mode displays targets of which detection probability is low.)
: General mode used when the nine modes above are not applicable.

[Page 1] [5] Auto STC / FTC (Auto Sea / Rain) Detects unwanted waves such as rain / snow clutter and sea clutter and automatically suppresses When the sea state or weather changes, this function automatically performs suppression processing in accordance with the situation. Suppression processing is not full automatic, and requires the operator to adjust the afterimages of them. unwanted waves. To adjust the afterimage of sea clutter, use the [SEA] dial. To adjust the afterimage of rain / snow clutter, use the [RAIN] dial. In areas where the density of unwanted waves is low, unwanted waves may remain being judged as targets. Thus, use the automatic clutter suppression mode together with the video process mode. Characteristics of the automatic clutter suppression function. Off AUTO Sea AUTO Sea/Rain
: Disables the automatic clutter suppression function. Select off when rain / snow clutter and sea clutter are not strong.
: Automatically detects the strength of sea clutter, and performs the most suitable sea clutter suppression processing. Even when the strength of sea clutter varies depending on the wind direction, AUTO Sea performs the most suitable suppression processing. Land like islands can be displayed naturally. Since rain clouds outside sea clutter areas are recognized as land, there is no effect of suppressing rain / snow clutter.
: Along with AUTO Sea, AUTO Rain automatically detects the strength of rain / snow clutter, and performs the most suitable rain
/ snow clutter suppression processing. When rain clouds are scattered about, AUTO Rain performs rain
/ snow clutter suppression processing for only the rain-cloud areas. Since land is recognized as rain clouds, land videos become obscure.

[Page 4] [1] - [7] Trails Setting Same functions as in the Trails Setting menu described in Section 3.8.2.
[Page 5] [1] Gain Offset Corrects gain while the function mode is called. Since the displayed noise level varies depending on the combination of the video process mode and the interference rejection level, gain needs fine adjustment for always obtaining the highest level. The gain correction function saves the correction value set by the gain adjust in each function mode, so it can obtain the highest gain without the gain adjust being operated when the function mode is changed. To set high gain, set a value on the + side. To set low gain, set a value on the - side. When the radar interference rejection level is increased, the noise level is lowered. Thus, set a gain correction value to the + side. When the video process mode 3Scan CORREL , 4Scan CORREL , or 5Scan CORREL is used, the noise level is lowered. Thus, set a gain correction value to the + side. When the video process mode Remain or Peak Hold is used, noise is hard to disappear. Thus, set a gain correction value to the - side. 3

[I] Resolution between adjacent targets and swapping
There are the following limitations on use of the target during automatic target tracking Depending on the particular distance and echo size, resolution between adjacent targets during automatic target tracking usually ranges somewhere between 0.03 to 0.05 NM. If multiple targets approach each other, resolution will become about 0.05 NM and this may cause the system to regard them as one target and thus to swap them or lose part of them. Such swapping or less of targets may also occur if the picture of the target being tracked is affected by rain/snow clutter returns or sea clutter returns or moves very close to land. USAGE OF TARGET TRACKING FUNCTION The intensity of echoes and the tracking function have a correlationship, and thus the target will be lost if no echoes are detected during six scans in succession. If a lost target exists, therefore, radar gain must be increased to support detection of the target. If, however, radar gain is increased too significantly, sea clutter returns or other noise may be erroneously detected and tracked as a target, and resultingly, a false alarm may be issued. tracking To execute accurate tracking, it becomes necessary first to appropriately adjust the [GAIN], [SEA] and [RAIN] dials of the radar so that the target to be acquired and tracked id clearly displayed on the radar display. Inappropriate settings of these adjustments reduce the reliability / accuracy of automatic tracking.

Now, it will be described briefly who the collision avoidance is positioned among the navigational aid problems. The navigation pattern of all mobile craft constitutes a system with some closed loops regardless of the media through which the mobile craft travels, whether air, water, the boundary between air and water, or space. This pattern consists of two closed loops in principle, one of which is a collision with another mobile craft and the other is a loop of finding a right and safe way to reach a predeterminate destination. Fig. 5-1 shows the conceptual diagram of navigation pattern by MR. E.W. Anderson. The closed loop of collision avoidance is shown on the left side and the closed loop of finding a right course on the right side. Fig. 5-1 Navigation Pattern Marine Accidents and Collisions Among marine accidents, collision accidents have been highlighted as the tonnages and speeds of ships become higher along with the increase in traffic at sea. If a tanker carrying dangerous articles such as crude oil collides with any other vessel, then not only the vessels involved with the accident but other vessels in the vicinity, port facilities, inhabitants in the coastal area as well as marine resources may also suffer immeasurable damages and troubles. Collision accidents have a high percentage of the marine accidents that have occurred in recent years. To cope with these problems, any effective measures are needed and some equipment to achieve collision avoidance requirements have been developed at rapid strides. 5-3 5.1 Preparation
Basic Concept of Collision Avoidance There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to predict that two or more vessels will happen to occupy the same point at the same time, while collision avoidance is to maneuver vessels not to occupy the same point at the same time. In practical operation of vessels, a spot of collision has to be deemed to be a single point but a closed zone. This closed zone is conceptually defined as a CPA (Closest Point of Approach). In collision prediction, the time to be taken until a ship reaches the CPA is defined as a TCPA (Time to CPA). Fig. 5-2 shows a diagram caked Collision Triangle. Target Vessel True Vector TCPATime to CPA Target vessel CPA Collision Triangle Relative Vector 5 Own Ship Fig. 5-2 Collision Triangle Own Ship True Vector CPA ring 5-4 Relative Vector and True Vector From two points of view, collision prediction and avoidance, it is necessary to obtain the relative vector of other ship for prediction and the true vector of other ship for collision avoidance in order to grasp other ships aspect. The relationship between the relative vector and true vector is shown in Fig. 5-3. Both rough CPA and TCPA can be obtained easily from the relative speed vector of other ship. This method has an advantage that the risks of collision with all other ships within the radar range can be seen at a glance. On the other hand, the course and speed of other ship can easily be obtained from its true speed vector, enabling other ships aspect to be seen at a glance. Thus, the aspects of other ships (transverse, outsail, parallel run, reverse run, etc...) as described in the act of prevention of collision at sea can be readily grasped. If there is a risk of collision with other ship, the operator can determine which rule to be applied and how to operate own ship. Target ship true vector N O Vo N VT T A R VO: Own ship's speed O: Own ship's course VT: Other ship's true speed T: Target ship's true course VR: Target ship's relative speed R: Target ship's relative course A: Aspect VR Relative vector Own ship true vector Fig. 5-3 Relative Vector and True vector CPA Radar and Collision Avoidance Radar is still playing an important roll for collision prevention and positioning. A plotter is used to further enhance the radar functionality. The plotter is capable of plotting other positions of other ships in 3 to 6 minute intervals to monitor their movement. The plots of other ships represent their tracks relative to own ship, and it is shown whether there is a risk of collision, namely CPA and TCPA can be obtained. This method using a plotter is fairly effective, but the number of target ship, which is manually plotted, is limited and it takes several minutes to measure those. 5-5 5.1 Preparation

Association target 2. Activated AIS target 3. Sleeping AIS target 5-7 If the number of targets at the same priority level exceeds the allowable maximum, they are displayed in the following priority order:
5.1 Preparation
The vector of an AIS target is to be displayed with a vector over ground or over water, depending on the speed sensor setting and current offset setting. The type of the currently displayed vector can be confirmed by viewing the setting of the stable mode. When GND is displayed for the stability mode (upper left of the display on page 2-2):
When Sea is displayed for the stability mode (upper left of the display on page 2-2):
Vector over ground Vector over water When the vector of an AIS target is displayed with a vector over water, the system has converted the AIS target's vector over ground to the vector over water according to the data received from the AIS and the own ship's information. Note: When the AIS target's symbol is activated but the vector is not displayed, the following are probable causes of the trouble:
COG/SOG is not yet input from the GPS. The selected speed sensor is malfunctioning. Types and Definitions of Association Target Symbols When a tracked target and an AIS target are decided as identical, it is displayed with either of the following symbols:

In each mode, a vector length can be freely changed for a time interval of 1 to 60 minutes. To switch between the true vector mode and relative vector mode, press the [VECT R/T] key.
[I] Vector Mode Selection True Vector Mode (Not used on the JPL-600-MK2 for VTS) In the true vector mode, the direction of a target vector indicates the true course of the target and its vector length is proportional to its speed. However, CPA Ring cannot appear in this mode. HL True vector The relative vector is not displayed 5-9 5.1 Preparation
Relative Vector Mode (Not used on the JPL-600-MK2 for VTS) The relative vector does not represent the true motion of the target, but its relative relation with own ship. This means that a target with its relative vector directed to own ship (passing through the CPA Limit ring) will be a dangerous target. In the Relative Vector mode, it can be seen at a glance where the CPA Limit of the dangerous target is. 5 HL The true vector is not displayed Relative vector CPA ring Therefore, the True / Relative mode shall optionally be used for the purpose of observation: the True vector mode for grasping the true aspect of a target, and the Relative vector mode for grasping a targets closest point of approach (CPA).
[II] Vector Length (Vector Time) The vector length of a target is proportional to its speed, and the vector time can be switched in a range of 1 to 60 minutes. The diagram below illustrates a vector length of a target for 6 minutes, and the tip of the vector represents the targets position expected to reach 6 minutes later. HL Future predicted position

5.2 TARGET TRACKING OPERATION This section explains how to use the target tracking function. The target tracking function automatically tracks a target, and displays the target's course and speed as vectors. The target tracking function calculates CPA and TCPA, and issues an alarm as needed. The tracking data is erased from memory when the power is turned off or during transmission standby. CAUTION Tracking target information such as vector, target numerical data, and alarms may contain some errors. Also, targets that are not detected by the radar cannot be acquired or tracked. In setting an automatic acquisition zone, it is necessary to adjust the gain, sea clutter suppression and rain clutter suppression to ensure that target echoes are displayed in the optimum conditions. No automatic acquisition zone alarms will be issued for targets undetected by the radar. 5 5-16 5.2.1 Acquiring Target [ACQ]
Target acquisition can be performed on two modes, Automatic and Manual, and both modes can be used at the same time. Automatic acquisition Note: If the number of targets being tracked has reached the allowable maximum and other targets
(not being tracked) go into the acquisition/activation zone, automatically acquired targets are canceled in ascending order of danger.

Lost Target Alarm Attention
If the gain, sea clutter suppression, rain/snow clutter suppression are not adjusted adequately, the lost target alarm may be easily generated. So such adjustments should be mad carefully. When it is impossible to continue tracking any acquired and tracked target, or the data of AIS target cannot received for a specified time, the LOST alarm will be generated. The typical causes for alarm generation are shown below, but not limited to the following:
The target echo is very weak. The target is shadowed by a shore or a large ship and its echo is not received. The target echo is blurred by sea clutter returns. If a target under tracking goes out of a range of 32 nm and can no longer be tracked, it is canceled without a lost target alarm.

(TRIAL MANEUVER)
(Not used on the JPL-600-MK2 for VTS) Attention
Trial maneuvering is to simulate own ships course and speed in the conditions that the course and speed of a target ship are unchanged as they are. As the situation is different from any actual ship maneuvering, set values with large margins to CPA Limit and TCPA Limit. The trial maneuvering is the function of simulating own ships course and speed for collision avoidance when a dangerous target appears. When the own ship's course and speed are entered in manual mode, the trial maneuvering function checks if pre-acquired or pre-activated targets are dangerous. The ranges of course and speed to be entered manually:
Course: 360 (in 0.1 intervals)..........................................................................[EBL] dial 0 to 100 kn (in 0.1 kn steps) ...................................................................[VRM] dial Speed:
5-57 5.7 Trial Maneuvering
Trial Maneuvering in the True Vector Mode In the True Vector mode, calculations are performed according to the values set by Trial Speed, Trial Course and other features, and the result is displayed as a bold-line that represents the change of own ships vector as shown in the figure below (an example of the course changed to the right). In this figure, the dangerous target forward left becomes safe as a result of simulation. The tracked target information indicates the current CPA and TCPA values regardless of the result of simulation.

For this purpose, the operator has to observe the radar displays after fully understanding the advantages and disadvantages that the radar has. For better interpretation of radar display, it is important to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the naked eyes and their echoes on the radar display. Various types of radar display will be explained below. RADAR WAVE WITH THE HORIZON Radar beam radiation has the nature of propagating nearly along the curved surface of the earth. The propagation varies with the property of the air layer through which the radar beam propagates. In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than the distance to the optical horizon. The distance (D) is given by the following formula:
D=2.23(
h1 +
h2
)(nm) h1: Height (m) of radar scanner above sea level h2: Height (m) of a target above sea level Figure 6. is a diagram for determining the maximum detection range of a target that is limited by the curve of the earth surface in the normal propagation. Figure 6.1 6-1 6.1 Radar Wave with the Horizon
D (nm) 6 Detective Range Figure 6.2 Height of Target Height of Radar Scanner When the height of scanner is 10 m for instance,
(b)
(a) A target that can be detected at the radar range of 64 nm on the radar display is required to have a height of 660 m or more. If the height of a target is 10 m, the radar range has to be approx. 15 nm. However, the maximum radar range at which a target can be detected on the radar display depends upon the size of the target and the weather conditions, that is, the radar range may increase or decrease depending upon those conditions. 6-2 6.2 STRENGTH OF REFLECTION FROM THE TARGET The signal intensity reflected from a target depends not only on the height and size of the target but also on its material and shape. The echo intensity from a higher and larger target is not always higher in general. In particular, the echo from a coast line is affected by the geographic conditions of the coast. If the coast has a very gentle slop, the echo from a mountain of the inland appears on the radar display. Therefore, the distance to the coast line should be measured carefully. Mountain displayed on the radar display HL Sea shore line not displayed on the radar display. Figure 6.3 Table 6.1 shows the graph indicating the relation between the target detection distance and the radar reflection cross-sectional area (RCS) with regard to the type and the height of the target in a situation in which the weather is good, the sea state is calm and the radio wave propagation is normal. As revealed by this table, even on the same sea shore line, detection distance greatly differs depending on the height of the target from the surface of the sea. Furthermore, because the target detection distance is greatly influenced by the shape and material of the target and environmental conditions, such as the sea state, weather, and radio wave propagation, caution should be taken when detecting distance of target. 6-3 6.2 Strength of Reflection from the Target

Reflection from the sea surface is called "sea clutter," and reflection from rain and snow is called "rain and snow clutter,"
and those spurious waves must be eliminated by the clutter rejection function.
[I] Sea clutter Sea clutter appears as an image radiating outwardly from the center of the radar display and changing depending on the size and the shape of waves. Generally, as waves become larger, image level of the sea clutter is intensified and the clutter far away is also displayed. When waves are large and the sea clutter level is high, it is difficult to distinguish sea clutter from a small boat whose reflection intensity is weak. Accordingly, it is necessary to properly adjust the sea clutter rejection function. Table 6.2 shows the relation between the sea state (SS) showing the size of waves generated by wind and the radar's detection probability. Table 6.2 Sea state and probability of target detection RCS 0.1m2 0.5 m2 1 m2 SS1 to 2 V V V SS2 to 3 V-M V V SS3 to 4 M-NV V-M V SS4 to 5 M-NV V-M S band radar (probability to detect a target at a distance of 0.4 NM) RCS 1m2 5 m2 10 m2 SS1 to 2 V-M V V SS2 to 3 M-NV V-M V SS3 to 4 SS4 to 5 M-NV V V-M X band radar (probability to detect a target at a distance of 0.7 NM) V: Detection probability of 80 %
M: Detection probability of 50 %
NV: Detection probability of less than 50 %
6-5 6.3 Sea Clutter and Rain and Snow Clutter
As shown in Table 6.3, the number of SS increases as the wind speed becomes high and the waves become large. Table 6.2 reveals that detection probability decreases from V (80 %) to NV (less than 50 %) as the number of SS increases. Therefore, even if the sea state is calm and a target clearly appears on the radar display, when the sea state becomes rough, target detection probability decreases resulting in difficulty of target detection by the radar. Table 6.3 Relation between Douglas sea state and average wind speed and significant wave height Sea state Average wind speed (kn) Significant wave height (m) 0 1 2 3 4 5 6

When observing such a target in the sea state (SS3) in which significant wave height exceeds 1.2 meters, detection probability is M-NV, as shown in Table 6.2, which indicates 50 % or less.
[II] Rain and snow clutter Rain and snow clutter is a video image that appears in a location where rain or snow is falling. The image changes according to the amount of rain (or the amount of snowfall). As precipitation increases, the image of rain and snow clutter becomes intensified on the radar display, and in the case of localized heavy rain, an image similar to the image indicating land is displayed in some cases. Furthermore, because radio waves tend to attenuate due to rain and snow, the ability to detect a target in the rain and snow clutter or a target beyond the rain and snow clutter may decrease. The amount of attenuation depends on the transmission frequency, antenna beam width, and the pulse length. Figure 6.3 and Figure 6.4 show examples in which detection distance is reduced due to the influence of precipitation. Because of this, a target, which clearly appeared up to 10 NM by an X band radar
(pulse width of 0.8 s) when it was not raining, may become dimly visible up to 5 NM when the amount of rain becomes 4 millimeters per hour. Furthermore, when comparing the X band radar with the S band radar, target detection distance decreases less when an S band radar is used, which means it is influenced less by precipitation. 6-6 Figure 6.3 Decreased target detection distance by S band radar due to precipitation

[III] Coping with sea clutter and rain and snow clutter When the weather is bad and the ocean is rough, the use of an S band radar is effective because the radar is not influenced by sea clutter so much and attenuation due to rain drops is small. When an X band radar is used, reducing the pulse width will reduce the influence by spurious waves, and also the spurious wave rejection function effectively works; therefore, the use of short pulse is effective when the weather is bad. By using image processing functions PROC 1 to 3, it is expected that spurious waves are further suppressed. Since optimal settings for those items can be automatically made by using the function mode, it is recommended that FUNC Storm or FUNC Rain be used by selecting the function mode when the weather is bad. For details of the function mode, see Chapter 3.9. However, these functions may make some targets invisible, particularly targets with higher speeds. 6 6-8 6.4 FALSE ECHOES The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear by the following causes that are well known:
[I] Shadow When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast. Whether there are some false echoes due to shadows can be checked monitoring the sea clutter returns, in which there may be a part of weak or no returns. Such shadows appear always in the same directions, which the operator should have in mind in radar operation.
[II] Side Lobe Effect A broken-line circular arc may appear at the same range as the main lobe of the radar beam on the radar display. This type of false echo can easily be discriminated when a target echo appears isolated.
(See Figure 6.5) HL Figure 6.5
[III] False Echo by Secondary Reflection When a target exists near own ship, two echoes from the single target may appear on the radar display. One of those echoes is the direct echo return from the target and the other is the secondary reflection return from a mast or funnel that stands in the same direction as shown in Figure 6.6. Radar scanner Funnel Direct microwave HL Actual target Secondary reflection of microwave Figure 6.6 6-9 False echo from funnel
[IV] False Echo by Multiple Reflection When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.7, multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target. 6.4 False Echoes
[V] Second Time Echoes Figure 6.7 The maximum radar detection range depends upon the height of the scanner and the height of a target as described in the section of The Horizon for Radar Beam Radiation. If a so-called duct occurs on the sea surface due to a certain weather condition, however, the radar beam may propagate to a abnormally long distance, at which a target may be detected by the radar. For instance, assuming that the pulse length is MP3 (on the repetition frequency of 1400 Hz), the first pulse is reflected from a target at about 58 NM or more and received during the next pulse repetition time. In this case, a false echo (second time echo) appears at a position that is about 58 NM shorter than the actual distance. If the false echo appears at 5 NM on the radar display, the true distance of the target is 5+58=63 NM. On the pulse length is SP1 (on the repetition frequency of 2250 Hz), a false echo may appear at a position that is about 36 NM shorter than the actual distance. This type of false echo can be discriminated by changing over the range scale (the repetition frequency), because the distance of the target changes accordingly. If second time echo is appeared, the use of Economy mode in PRF menu is effective. Otherwise, Stagger Trigger menu set to on. (See section 3.8.3) 6 6-10
[VI] Radar Interference When another radar equipment using the same frequency band as that on own ship is near own ship, a radar interference pattern may appear on the radar display. This interference pattern consists of a number of spots which appear in various forms. In many cases, these spots do not always appear at the same places, so that they can be discriminated from the target echoes. (See Figure 6.8) HL HL Figure 6.8 If radar equipment causing an interference pattern and this radar are of the same model, their transmitting repetition frequency is nearly the same. As a result, interference patterns may be displayed concentrically. In this case, the interference patterns cannot be eliminated by using only the interference reflector function, so press [TX/PRF] key several times to fine-tune the transmitting repetition frequency. An interference suppressing effect can be heightened by applying a different transmitting repetition frequency to the interference pattern source radar and this radar. 6-11 6.5 Display of Radar Transponder
6.5 DISPLAY OF RADAR TRANSPONDER
(SART) The SART (Search and rescue Radar Transponder) is a survival device authorized by the GMDSS (Global Maritime Distress and Safety System), which is used for locating survivors in case that a distress accident occurs at sea. The SART is designed to operate in the 9 GHz frequency band. When receiving the 9 GHz radar signal (interrogating signal) transmitted from the radar equipment on a rescue ship or search aircraft, the SART transmit a series of response signals to inform the distress position to the rescue and search party.

(a) The proper fastening torque of the fitting bolts (M8) is 1176 to 1470 N-cm (120 to 150 kgf-cm) (which makes the inside water-tight and protects the packing against permanent compressive strain). The packing start producing from the cover at a torque of approximately 1470N-cm (150 kgf-cm). Do not fasten the bolts with a torque exceeding the specified value. Otherwise, the screws may be broken.
(b) Use an offset wrench of 11 mm 13 mm or a double-ended wrench of 13 mm 17 mm (not longer
(c) Screw all the bolts by hand first to prevent them playing, then fasten them evenly in order not to cause one-sided fastening. (Fasten the bolts with 25 % of the required torque at the first step.) than 200 mm).
*: Fasten the bolts in the diagonal order. 8-3 8.2 Maintenance on each Unit
(1) Radiator Attention
If the radiator front face (radiation plane) is soiled with smoke, salt, dust, paint or birds droppings, wipe it with a piece of soft cloth wetted with alcohol or water and try to keep it clean at all times. Otherwise, radar beam radiation may attenuate or reflect on it, resulting in deterioration of radar performance.
Never use solvents of gasoline, benzine, trichloroethylene and ketone for cleaning. Check up and clean the radiator.
(2) Rotating section
(a) Supply Oil Seal An scanner unit with a grease nipple needs grease supply. Remove the cap of the grease nipple on the front of the radiator support, and supply grease with a grease gun. Make the oiling every six months. The oil quantity shall be approximately 100 g, which is as much as the grease comes out of the oil seal. Use the grease of Mobilux 2 of Mobil Oil.
(b) Oiling gears
(c) Mounting legs Apply grease evenly to the tooth surfaces of the main shaft drive gear and the encoder drive gear with a spreader or brush. Oiling in short intervals is more effective to prevent the gears from wear and tear and extend their service life, but oil at least every six months. Use Mobilux2 of Mobile Oil. Check the mounting legs and mounting bolts of the scanner unit case for corrosion at intervals and maintain them to prevent danger. Apply paint to them once a half year because painting is the best measure against corrosion. 8 8-4 8.2.2 Display Unit NCD-2034A WARNING When cleaning the display screen, do not wipe it too strongly with a dry cloth.

You do not face any danger during normal operation, but sufficient cares are required for maintenance, inspection and adjustment of their internal components. (Maintenance, check-up and adjustment of the inside of the equipment are prohibited except by maintenance specialists.) High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from electric shock, but even voltages of hundred volts may sometimes lead to a death from electric shock. To prevent such an accident, make it a rule to turn off the power switch, discharge capacitors with a wire surely earthed on an end make sure that internal parts are no longer charged before you touch any parts inside these devices. At the time, wearing dry cotton gloves ensures you further to prevent such danger. It is also a necessary caution to put one of your hands in the pocket and not to use your both hands at the same time. It is also important to select a stable foothold always to prevent additional injuries once you were shocked by electricity. If you were injured from electric shock, disinfect the burn sufficiently and get it taken care of promptly. What to do in case of electric shock When finding a victim of electric shock, turn off the power source and earth the circuit immediately. If it is impossible to turn off the circuit, move the victim away promptly using insulators such as dry wood plate and cloth without touching the victim directly. In case of electric shock, breathing may stop suddenly if current flows to the respiration center in the brain. If the shock is not so strong, artificial respiration may recover breathing. When shocked by electricity, the victim will come to look very bad with weak pulse or without beating, resulting in unconsciousness and rigidity. In this case, it is necessary to perform an emergency measure immediately. FIRST-AID TREATMENTS First-aid treatments As far as the victim of electric shock is not in dangerous condition, do not move him and practice artificial respiration on him immediately. Once started, it should be continued rhythmically.
(1) Do not touch the victim confusedly as a result of the accident, but the rescuer may also get an electric shock.
(2) Turn off the power source calmly and move the victim away quietly from the electric line.
(3) Call a physician or ambulance immediately or ask someone to call a doctor.
(4) Lay the victim on this back and loosen his necktie, clothes, belt, etc.
(5) a. Examine the victims pulse.
(6) Open the victims mouth and take out artificial teeth, cigarette or chewing gum if any. Keep his mouth open, stretch his tongue and insert a towel or the like in his mouth to prevent the tongue from suffocating. (If it is hard to open his mouth due to set teeth, open it with a screwdriver and insert a towel in this mouth.) b. Examine his heartbeat bringing your ear close to his heart. c. Examine his breathing bringing the back of your hand or your face close to his face. d. Check the size of the pupils of his eyes.
(7) Then, wipe his mouth so that foaming mucus does not accumulate inside. When pulse is beating but breathing has stopped
(Mouth-to-mouth respiration) Fig. 1
(1) Tilt the victims head back as far as this face looks back. (A pillow may be inserted his neck.)
(2) Push his jaw upward to open his throat wide (to spread his airway).
(3) Pinch the victims nostrils and take a deep breath, block his mouth completely with yours and blow into his mouth strongly. Take a deep breath again and blow into his mouth. Continue this 10 to 15 times a minutes (blocking his nostrils).
(4) Carefully watch that he has recovered his natural breathing and atop practicing artificial respiration. If it is difficult to open the victims mouth, insert a rubber or vinyl tube into one of his nostrils and blow into it blocking the other nostril and his mouth completely.
(6) When the victim recovers consciousness, he may try to stand up suddenly, but let him lie calmly and serve him with a cup of hot coffee or tea and keep him warm and quiet. (Never give him alcoholic drinks.)
(5) Method of mouth-to-mouth respiration by raising head
(1) Raise the victims head. Support his forehead with one of your hand and his neck with the other hand. 1 When you tilt his head backward, the victim, in most cases, opens his mouth to the air. This makes mouth-to mouth respiration easy.
(2) Cover his mouth as widely as possible with yours and press your cheek against his nose 2 or, pinch his nostrils with your fingers to prevent air from leaking. 3
(3) Blow into his lungs. Continue blowing into his mouth until his breast swells. Blow into his mouth as quickly as possible for the first 10 times. Fig. 1 Mouth-to mouth respiration When both pulse and breathing have stopped Perform the (Cardiac massage) Fig. 2 and (Mouth-to-mouth respiration) Fig. 1 When no pulse has come not to be felt, his pupils are open and no heartbeat is heard, cardiac arrest is supposed to have occurred and artificial respiration must be performed.
(1) Place your both hands, one hand on the other, on the lower one third area of his breastbone and compress his breast with your elbows applying your weight on his breast so that it is dented about 2cm (Repeat compressing his breast 50 times or so a minutes). (Cardiac massage) In case of one rescuer, Repeat cardiac massages about 15 times and blow into his mouth 2 times quickly, and repeat this combination. In case of two rescuers, One person repeats cardiac massages 15 times while the other person blow into his mouth twice, and they shall repeat this combination. (Perform the cardiac massage and mouth-to-mouth respiration)
(3) Examine his pupils and his pulse sometimes. When the both have returned to normal, stop the artificial respiration, serve him with a cup of hot coffee or tea and keep him warm and calm while watching him carefully. Commit the victim to a medical specialist depending on his condition. (Never give him alcoholic drinks.) To let him recover from the mental shock, it is necessary for persons concerned to understand his situations and the necessary treatment.

When conducting maintenance, make sure to turn the main power off. Failure to comply may result in electrocution. Turn off the main power before cleaning the equipment. Especially when a rectifier is used, make sure to turn it off since voltage is still outputted from the rectifier even after the indicator and the radar are turned off. Failure to comply may result in equipment failure, or death or serious injury due to electric shock. When conducting maintenance work on the scanner, make sure to turn its main power off. Failure to comply may result in electrocution or injuries.
- iii -
DANGER Make sure to turn off the scanner safety switch. Failure to comply may result in injuries caused by physical contact with the rotating scanner. WARNING Never directly touch the internal components of the scanner or indicator. Direct contact with these high-voltage components may cause electrocution. For maintenance, inspection, or adjustment of equipment components, consult with our branch office, branch shop, sales office, or our distributor in your district. To contact our sales department, branch offices, branch shops, and sales offices:
Please refer to the "Office List" at the end of the document. Do not get close to the radiant section of the scanner. It is a rotating part, and it may cause injuries if it suddenly starts rotating and consequently hits the body. It is recommended that the radiant section be installed at a high place such as on the roof of the wheelhouse, on the flying bridge, on the trestle, or on the radar mast so that no one can get close to it. When any work must be done on the scanner, make sure to turn the safety switch off.
- iv -
WARNING Microwave radiation level:
Keep out from a distance closer than that specified below for each type of scanner when it is transmitting. Being within the specified distance from the center of the front face of the scanner may cause microwave exposure which could result in injuries (especially of the eyes). NKE-2103/2254 (radiation levels: 10 W/m2): 0.6 m NKE-1130 (radiation levels: 10 W/m2): 1.1 m NKE-1130 (radiation levels: 100 W/m2): 25 cm Make sure to install the scanner at a place higher than human height. Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. When it is necessary to get close to the scanner for maintenance or inspection purposes, make sure to turn the indicator power switch to "OFF" or "STBY."
Direct exposure to electromagnetic waves at close range will have adverse effects on the human body. When conducting maintenance work, make sure to turn off the power and unplug the power connector J1 of the radar process unit so that the power supply to the equipment is completely cut off. Some equipment components can carry electrical current even after the power switch is turned off, and conducting maintenance work without unplugging the power connector may result in electrocution, equipment failure, or accidents.

WARNING When cleaning the display screen, do not wipe it too strongly with a dry cloth. Also, do not use gasoline or thinner to clean the screen. Failure to comply will result in damage to the screen surface. Do not change MBS Level/Area unless absolutely necessary. Incorrect adjustment will result in deletion of nearby target images and thus collisions may occur resulting in death or serious injuries. When disposing of used lithium batteries, be sure to insulate the batteries by attaching a piece of adhesive tape on the and terminals. Failure to comply may cause heat generation, explosion, or fire when the batteries get shorted out. CAUTION Use the radar only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on the radar display may cause accidents such as collisions or running aground.
- vi -
CAUTION Use target tracking function only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on tracking target information may cause accidents. Tracking target information such as vector, target numerical data, and alarms may contain some errors. Also, targets that are not detected by the radar cannot be acquired or tracked. Making the final navigation decision based only on the radar display may cause accidents such as collisions or A malfunction may occur if the power in the ship is instantaneously interrupted during operation of the radar. In this case, the power should be turned on again. When using the [AUTO SEA] function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the [AUTO SEA] function, make sure to choose the most appropriate image noise suppression level. When using the [AUTO RAIN] function, never set the suppression level too high canceling out all image noises from the rain or snow at close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the [AUTO RAIN] function, make sure to choose the most appropriate image noise suppression level.
- vii -
CAUTION When setting a guard zone, make sure to properly adjust gain, sea-surface reflection suppression level, and rain/snow reflection suppression level so that the optimal target images are always on the radar screen. The guard zone alarm will not be activated for targets undetected by the radar, and it may result in accidents such as collisions. The simulation function is used exclusively for deciding whether or not target tracking is properly operating. Therefore, never use this function unless you wish to check target tracking operations. Note especially that, if this function is used during actual navigation, simulated targets are displayed and may become confused with other actual targets. Therefore, never use this function during actual navigation. Optimal values have been set for VD LEVEL and CONSTANT; therefore, never change their values unless absolutely necessary. Failure to comply may result in accidents that would lower target tracking performance. Make sure to shut off the main power before replacing parts. Failure to comply may result in electrocution or equipment failure. When replacing magnetrons, make sure to shut off the main power and let the equipment stand for more than 5 minutes to discharge the high-voltage circuit. Failure to comply may result in electrocution.
- viii -
CAUTION Make sure to take off your watch when your hand must get close to the magnetron. Failure to comply may result in damage to the watch since the magnetron is a strong magnet. Make sure that two or more staff member work together when replacing the LCD. If only one person attempts to replace the LCD, he/she may drop it and become injured. Do not directly touch the inverter circuit of the LCD display with a bare hand since high voltage temporarily remains in the circuit even after the main power is shut off. Failure to comply may result in electrocution. Any adjustments must be made by specialized service personnel. Incorrect settings may result in unstable operation. Do not make any adjustments during navigation. Failure to comply may result in adverse effects on the radar function which may lead to accidents or equipment failure. Any adjustments must be made by specialized service personnel. Failure to comply may result in accidents or equipment failure. Do not make any adjustments during navigation. Failure to comply may result in adverse effects on the radar function which may lead to accidents or equipment failure.

POWER ON AND START THE SYSTEM OBSERVE AND ADJUST VIDEO ACQUIRE AND MEASURE DATA END THE OPERATION AND STOP THE SYSTEM Each operation is described in detail below. 3-1 3 3.1 Operation Flow
Wait for about 2 seconds before turning on the CAUTION A malfunction may occur if the power in the ship is instantaneously interrupted during operation of the radar. In this case, the power should be turned on again. Attention power again. 3.1.1 Power ON and Start the System
Immediately after the radar is installed, at start of the system after it has not been used for a long time, or after the magnetron is replaced, preheat the equipment in the standby state for 20 to 30 minutes before setting it into the transmit state.
If the preheating time is short, the magnetron causes sparks, resulting in its unstable oscillation. Start transmission on a short-pulse range and change the range to the longer pulse ranges in turn. If the transmission is unstable in the meantime, immediately place the system back into the standby state and maintain it in the standby state for 5 to 10 minutes before restarting the operation. Repeat these steps until the operation is stabilized. 3-2 Procedures 1 Check that the ships mains are turned on. 2 Press the [STBY] key. The system is turned on, and the preheating time is displayed. Preheat is indicated upper left of the display. 3 Wait until the preheating time is over. When the preheating time is over, the preheating time screen disappears, and Preheat upper left of the display changes to Standby . 4 Press the [TX / PRF] key. The radar will start transmission and the antenna will start rotating. Standby upper left of the display changes to Transmit . Note: The radar does not start transmission if you Press the [TX / PRF] key while Preheat is indicated. 3.1.2 Observe and Adjust Video Procedures 1 Press the [RANGE+] key or [RANGE-] key to set the range to the scale required for target observation. 2 Turn the dials [GAIN / PL], [AUTO-SEA], and [AUTO-RAIN] to obtain the clearest targets.

Maintain the standby state if radar observation is restarted in a relatively short time. Only pressing the [TX / PRF] key starts observation. 2 Press the [STBY] key and the [TX / PRF] key together. The system will be turned off. 3 WARNING When conducting maintenance work, make sure to turn off the power and unplug the power connector J1 of the radar process unit so that the power supply to the equipment is completely cut off. Some equipment components can carry electrical current even after the power switch is turned off, and conducting maintenance work without unplugging the power connector may result in electrocution, equipment failure, or accidents. 3-4 3.2 OBSERVE AND ADJUST VIDEO 3.2.1 Adjust Monitor Brilliance [BRILL]
Procedures 1 Obtain the best-to-see display with optimum brilliance by turning the
[BRILL] dial at the lower right of the LCD monitor. Turning the [BRILL] dial clockwise increases the brilliance of the entire display. Conversely, turning the [BRILL] dial counterclockwise decreases the brilliance of the entire display. In consideration of the ambient brightness, adjust display brilliance that is high enough to easily observe the radar display but does not glare. 3.2.2 Change Observation Range [RANGE + / - ]
Procedures 1 When increasing the observation range, press the [RANGE+] key. Increasing the observation range will enable a wider range to be observed. However, a video image is small and the ability to detect targets near own ship decreases. Therefore, when observing the vicinity of own ship, use the smaller observation range. 2 When decreasing the observation range, press the [RANGE-] key. Decreasing the observation range will enable the vicinity of own ship to be enlarged. However, caution must be taken because video images of the area beyond the observation range cannot be displayed. 3-5 3.2 Observe and Adjust Video
3.2.3 Tune CAUTION Normally, use the automatic tune mode. Use the manual tune mode only when best tuning is not possible in the automatic tune mode due to deterioration of magnetron. 3 This radar system provides the automatic tune mode and the manual tune mode. The automatic tune mode automatically adjusts the tuning of the transmitting frequency and the receiving frequency, and the manual tune mode enables tuning to be adjusted by using the dial located on the operation unit. The tune mode currently being used is displayed in the tune mode switching (lower left of the display on page 2-18). When using the automatic tune mode Procedures 1 Put the cursor on the tune mode switching (lower left of the display on page 2-18) and press the [ENT] key. The automatic tune mode is selected and AUTO is displayed in the tune mode field. Tune adjustment is automatically conducted. Tune is adjusted at the start of transmission, at the change of the range or pulse length. Tune adjustment is completed within several seconds. When using the manual tune mode 1 Put the cursor on the tune mode switching (lower left of the display on page 2-18) and press the [ENT] key to set the manual tune mode. The automatic tune mode is cancelled, and MAN is displayed in the tune mode field. 2 Press the [MULTI] dial to set the ( Tune ) mode. Tune is displayed in the multi-dial mode (lower left of the display on page 2-3). 3 Turn the [MULTI] dial to adjust tune. Make adjustments so that the tuning indication (upper left of the display on page 2-2) indicates the maximum. Procedures 3-6 3.2.4 Adjust Gain [GAIN / PL]
CAUTION If the gain is too high, unnecessary signals including receiver noise and false video increase resulting in reduction of visibility of targets. On the contrary, if the gain is too low, targets including ships and dangerous objects may not be clearly indicated. Procedures 1 Adjust noise of the display by turning the [GAIN / PL] dial until targets can be easily observed. Turning [GAIN / PL] dial clockwise increases gain. Turning [GAIN / PL] dial counterclockwise decreases gain. By increasing receiving gain, the range to observe radar video is widened. To observe densely crowded targets or short-range targets, reducing the receiving gain will enable the targets to be easily observed. 3-7 3.2 Observe and Adjust Video
3.2.5 Suppress Sea Clutter [AUTO-SEA]
CAUTION When using the sea clutter suppression function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the sea clutter suppression function, make sure to choose the most appropriate image noise suppression level. 3 Using the manual sea clutter suppression mode Procedures 1 Adjust the sea clutter returns of the display by turning the [AUTO-SEA]
dial until targets can be easily observed. Turning [AUTO-SEA] dial clockwise suppresses sea clutter returns. Turning [AUTO-SEA] dial counterclockwise intensifies sea clutter returns. The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving gain on a short range. Turning the [AUTO-SEA] dial clockwise heightens the effect of sea clutter suppression. However, be careful that excessive suppression causes low signal-strength targets such as buoys and boats to disappear from the radar display. 3-8 Using the automatic sea clutter suppression mode The sea clutter suppression in accordance with the intensity of sea clutter is possible. Use this mode when the sea clutter's intensity differs according to directional orientation. Procedures 1 Press the [AUTO-SEA] dial. The automatic sea clutter suppression mode is selected, and AUTO is displayed in sea clutter suppression (Sea) mode switching (lower left of the display on page 2-18). 2 Make adjustments by turning the [AUTO-SEA] dial. Even when the automatic sea clutter suppression mode is selected, turning the
[AUTO-SEA] dial can make fine adjustments manually. Note: When the automatic sea clutter suppression mode is selected, the automatic rain/snow suppression mode is switched to the manual mode. To select both the sea clutter suppression function and the rain/snow suppression function in the automatic mode, use the automatic rain/snow suppression mode. 1 Press the [AUTO-SEA] dial. The automatic sea clutter suppression mode is cancelled, and MAN is displayed in the sea clutter suppression (Sea) mode field. 3.2.6 Suppress Rain / Snow Clutter [AUTO-RAIN]
Cancellation CAUTION When using the rain clutter suppression function, never set the suppression level too high canceling out all image noises from the rain or snow at the close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the rain clutter suppression function, make sure to choose the most appropriate image noise suppression level. 3-9 3.2 Observe and Adjust Video
Using the manual rain / snow clutter suppression mode Procedures 1 Adjust the rain / snow clutter returns of the display by turning the
[AUTO-RAIN] dial until targets can be easily observed. Turning [AUTO-RAIN] dial clockwise suppresses rain / snow clutter returns. Turning [AUTO-RAIN] dial counterclockwise intensifies rain / snow clutter returns. When the [AUTO-RAIN] dial is turned clockwise, the rain / snow clutter suppression function suppresses rain / snow clutter returns and gets targets hidden by rain / snow clutter returns to appear of the display. However, be careful that excessive suppression may cause small targets to be overlooked. Since the rain / snow clutter suppression function also has the effect of suppressing sea clutter, the suppression efficiency improves when the [AUTO-RAIN] dial is used with the [AUTO-SEA] dial. In general, turn the [AUTO-RAIN] dial fully to the left. 3 Using the automatic rain / snow clutter suppression mode The rain / snow clutter suppression in accordance with the intensity of rain / snow clutter is possible. Use this mode when the rain / snow clutter's intensity differs according to directional orientation. Procedures 1 Press the [AUTO-RAIN] dial. The automatic rain / snow clutter suppression mode is selected, and AUTO is displayed in the sea clutter suppression (Sea) mode switching and the rain / snow clutter suppression (Rain) mode switching ( lower left on the display and on page 2-18) 2 Make adjustments by turning the [AUTO-RAIN] dial and the [AUTO-SEA]

: Use this mode to monitor a relatively short range, for example, bays and coasts where many boats and ships are running. (Importance is attached to resolution.)
: Use this mode to monitor a relatively long range, for example, the open sea.
(Importance is attached to long-range gain.)
: Use this mode to detect small targets such as fishnets of round haul netters hidden by sea clutter returns. (Importance is attached to sea clutter suppression, and gain to moving targets lowers.)
: Use this mode when many rain / snow clutter returns or sea clutter returns are detected in stormy weather. (Importance is attached to rain / snow clutter and sea clutter suppression, and gain slightly lowers.)
: Use this mode when only a few rain / snow clutter returns or sea clutter returns are detected.
: Use this mode when sea clutter is not strong but rain / snow clutter is strong. (Importance is attached to rain / snow clutter suppression, and gain slightly lowers.)
: Use this mode to detect flocks of sea birds.
: Use this mode to monitor utmost distances in the broad ocean.

[Page 5] [1] Gain Offset Corrects gain while the function mode is called. Since the displayed noise level varies depending on the combination of the video process mode and the interference rejection level, gain needs fine adjustment for always obtaining the highest level. The gain correction function saves the correction value set by the gain adjust in each function mode, so it can obtain the highest gain without the gain adjust being operated when the function mode is changed. To set high gain, set a value on the + side. To set low gain, set a value on the - side. When the radar interference rejection level is increased, the noise level is lowered. Thus, set a gain correction value to the + side. When the video process mode 3Scan CORREL , 4Scan CORREL , or 5Scan CORREL is used, the noise level is lowered. Th us, set a ga n correction value to the + side. i When the video process mode Remain or Peak Hold is used, noise is hard to disappear. Thus, set a gain correction value to the - side. 3

There are the following limitations on use of the target Attention acquisition and target tracking functions.
[I] Resolution between adjacent targets and swapping during automatic target tracking Depending on the particular distance and echo size, resolution between adjacent targets during automatic target tracking usually ranges somewhere between 0.03 to 0.05 NM. If multiple targets approach each other, resolution will become about 0.05 NM and this may cause the system to regard them as one target and thus to swap them or lose part of them. Such swapping or less of targets may also occur if the picture of the target being tracked is affected by rain/snow clutter returns or sea clutter returns or moves very close to land.
[II] Intensity of echoes and the target tracking function The intensity of echoes and the tracking function have a correlationship, and thus the target will be lost if no echoes are detected during six scans in succession. If a lost target exists, therefore, radar gain must be increased to support detection of the target. If, however, radar gain is increased too significantly, sea clutter returns or other noise may be erroneously detected and tracked as a target, and resultingly, a false alarm may be issued.
[III] Adverse effects of error sources on automatic tracking To execute accurate tracking, it becomes necessary first to appropriately adjust the [GAIN], [SEA] and [RAIN] dials of the radar so that the target to be acquired and tracked id clearly displayed on the radar display. Inappropriate settings of these adjustments reduce the reliability /
accuracy of automatic tracking. 5-1 5.1 Preparation
5.1 PREPARATION This section explains the features of the target tracking and AIS functions, and the initial setting for using each function. Target Tracking Function (Option) The target tracking function calculates the course and speed of a target by automatically tracking the target's move. The target tracking function enables the automatic acquisition of targets by using the automatic acquisition zone function. The target tracking function also enables the simulation of the ship maneuvering method to avoid collisions by using the trial maneuver function. (NCA-877WA) If the mode is ground stabilization, SOG/COG used for own ship's information in target tracking. If the mode is sea stabilization, SPD (speed through the water) / HDG (heading) used for own ship's information in target tracking. Maximum number of targets that can be tracked Trial maneuver function Normal edition NCA-877A High performance edition NCA-877WA 30 Not provided 100 Provided Note: ARPA Process Unit (NCA-877WA) or ATA Process Unit (NCA-877A) must be fitted on ships compliant to IMO. AIS (Automatic Identification System) function (Option) The AIS function shows the targets information on the radar display, using other ship's information sent out from the AIS unit. Note: AIS Process Unit must be fitted on ships compliant to IMO. 5 5-2 5.1.1 Collision Avoidance Problems of Collision Avoidance in Navigation Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be described briefly who the collision avoidance is positioned among the navigational aid problems. The navigation pattern of all mobile craft constitutes a system with some closed loops regardless of the media through which the mobile craft travels, whether air, water, the boundary between air and water, or space. This pattern consists of two closed loops in principle, one of which is a collision with another mobile craft and the other is a loop of finding a right and safe way to reach a predeterminate destination. Fig. 5-1 shows the conceptual diagram of navigation pattern by MR. E.W. Anderson. The closed loop of collision avoidance is shown on the left side and the closed loop of finding a right course on the right side. Fig. 5-1 Navigation Pattern Marine Accidents and Collisions Among marine accidents, collision accidents have been highlighted as the tonnages and speeds of ships become higher along with the increase in traffic at sea. If a tanker carrying dangerous articles such as crude oil collides with any other vessel, then not only the vessels involved with the accident but other vessels in the vicinity, port facilities, inhabitants in the coastal area as well as marine resources may also suffer immeasurable damages and troubles. Collision accidents have a high percentage of the marine accidents that have occurred in recent years. To cope with these problems, any effective measures are needed and some equipment to achieve collision avoidance requirements have been developed at rapid strides. 5-3 5.1 Preparation
Basic Concept of Collision Avoidance There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to predict that two or more vessels will happen to occupy the same point at the same time, while collision avoidance is to maneuver vessels not to occupy the same point at the same time. In practical operation of vessels, a spot of collision has to be deemed to be a single point but a closed zone. This closed zone is conceptually defined as a CPA (Closest Point of Approach). In collision prediction, the time to be taken until a ship reaches the CPA is defined as a TCPA (Time to CPA). Fig. 5-2 shows a diagram caked Collision Triangle. 5 Fig. 5-2 Collision Triangle 5-4 Relative Vector and True Vector From two points of view, collision prediction and avoidance, it is necessary to obtain the relative vector of other ship for prediction and the true vector of other ship for collision avoidance in order to grasp other ships aspect. The relationship between the relative vector and true vector is shown in Fig. 5-3. Both rough CPA and TCPA can be obtained easily from the relative speed vector of other ship. This method has an advantage that the risks of collision with all other ships within the radar range can be seen at a glance. On the other hand, the course and speed of other ship can easily be obtained from its true speed vector, enabling other ships aspect to be seen at a glance. Thus, the aspects of other ships (transverse, outsail, parallel run, reverse run, etc. ) as described in the act of prevention of collision at sea can be readily grasped. If there is a risk of collision with other ship, the operator can determine which rule to be applied and how to operate own ship. Target ship true vector N O Vo N VT T A R VO: Own ship's speed O: Own ship's course VT: Other ship's true speed T: Target ship's true course VR: Target ship's relative speed R: Target ship's relative course A: Aspect VR Relative vector Own ship true vector Fig. 5-3 Relative Vector and True vector CPA Radar and Collision Avoidance Radar is still playing an important roll for collision prevention and positioning. A plotter is used to further enhance the radar functionality. The plotter is capable of plotting other positions of other ships in 3 to 6 minute intervals to monitor their movement. The plots of other ships represent their tracks relative to own ship, and it is shown whether there is a risk of collision, namely CPA and TCPA can be obtained. This method using a plotter is fairly effective, but the number of target ship, which is manually plotted, is limited and it takes several minutes to measure those. 5-5 5.1 Preparation

Association target 2. Activated AIS target 3. Sleeping AIS target 5-7 If the number of targets at the same priority level exceeds the allowable maximum, they are displayed in the following priority order:
5.1 Preparation
The vector of an AIS target is to be displayed with a vector over ground or over water, depending on the speed sensor setting and current offset setting. The type of the currently displayed vector can be confirmed by viewing the setting of the stable mode. When GND is displayed for the stability mode (upper left of the display on page 2-2):
When Sea is displayed for the stability mode (upper left of the display on page 2-2):
Vector over ground Vector over water When the vector of an AIS target is displayed with a vector over water, the system has converted the AIS target's vector over ground to the vector over water according to the data received from the AIS and the own ship's information. Note: When the AIS target's symbol is activated but the vector is not displayed, the following are probable causes of the trouble:
COG/SOG is not yet input from the GPS. The selected speed sensor is malfunctioning. Types and Definitions of Association Target Symbols When a tracked target and an AIS target are decided as identical, it is displayed with either of the following symbols:

[I] Vector Mode Selection True Vector Mode A vector to represent a targets predicted position can be presented in the True vector or Relative vector mode. In each mode, a vector length can be freely changed for a time interval of 1 to 60 minutes. To switch between the true vector mode and relative vector mode, press the [VECT R/T] key. In the true vector mode, the direction of a target vector indicates the true course of the target and its vector length is proportional to its speed. In this mode, own ships vector is displayed as shown below. In this mode, the movements of other ships around own ship can be accurately and easily monitored. However, CPA Ring cannot appear in this mode. 5-9 5.1 Preparation
Relative Vector Mode The relative vector does not represent the true motion of the target, but its relative relation with own ship. This means that a target with its relative vector directed to own ship (passing through the CPA Limit ring) will be a dangerous target. In the Relative Vector mode, it can be seen at a glance where the CPA Limit of the dangerous target is. 5 Therefore, the True / Relative mode shall optionally be used for the purpose of observation: the True vector mode for grasping the true aspect of a target, and the Relative vector mode for grasping a targets closest point of approach (CPA).
[II] Vector Length (Vector Time) The vector length of a target is proportional to its speed, and the vector time can be switched in a range of 1 to 60 minutes. The diagram below illustrates a vector length of a target for 6 minutes, and the tip of the vector represents the targets position expected to reach 6 minutes later. HL Future predicted position

TARGET TRACKING OPERATION This section explains how to use the target tracking function. The target tracking function automatically tracks a target, and displays the target's course and speed as vectors. The target tracking function calculates CPA and TCPA, and issues an alarm as needed. The tracking data is erased from memory when the power is turned off or during transmission standby. 5.2.1 Acquiring Target [ACQ]
Target acquisition can be performed on two modes, Automatic and Manual, and both modes can be used at the same time. Automatic acquisition Note: If the number of targets being tracked has reached the allowable maximum and other targets (not being tracked) go into the acquisition/activation zone, automatically acquired targets are canceled in ascending order of danger. The position of the scanner shall be at the centre of the azimuth or range in the acquisition/activation zone.

* Data Base can contain 30 ship names. 5-22 5.2.6 Reference Target (Reference) The system can display the own ship's speed. To do so, it sets a reference target by tracking a target for which ground fixed. Attention
The reference target function is to be used if the own ship's speed cannot be displayed normally due to trouble such as a speed sensor malfunction. Do not use the reference target function except in emergencies.
If the speed or course of the own ship is changed or a new reference target is set, the displayed speed may take 3 minutes or more to reach the specified speed after the speed / course change or the setting. Even after 3 minutes or more has passed, the speed may differ from the specified speed depending on the tracking condition.
If a large radar echo such as a land target is set as a reference target, the vectors of the speed and other tracking targets will not be displayed correctly and may cause an accident.
If a sailing ship is set as a reference target, the vectors of the speed and other tracking targets will not be displayed correctly and may cause an accident.
If the REF. is selected for the speed sensor, the AIS function cannot be turned on.
If the reference target is lost or the target tracking function is stopped, the speed sensor is placed in manual mode MAN .
The loss of a reference target may have a major impact on the accuracy of the results for true speed and true course of the target and that own speed will be degraded.

The typical causes for alarm generation are shown below, but not limited to the following:
suppression are not adjusted adequately, the lost target alarm may be easily generated. So such adjustments should be mad carefully. The target echo is very weak. The target is shadowed by a shore or a large ship and its echo is not received. The target echo is blurred by sea clutter returns. If a target under tracking goes out of a range of 32 nm and can no longer be tracked, it is canceled without a lost target alarm. Lost Target Alarm Status Symbol on display Alarm characters Alarm sound Conditions Lost target 12 AIS12 Red Blinking Lost Beep sound (pee) Alarm acknowledgeable The alarm will sound once when a lost target symbol is displayed. Gyro Set Alarm The GYRO I/F in this system receives signals from a gyro. Even if the power is turned off, the system will follow up the gyro. However, the system stops the follow-up operation when the power of the master gyro is turned off or when any trouble occurs to the line. When the power of the master gyro is recovered, the Set Gyro alarm will be generated. If this alarm occurs, set the gyro.

TRIAL MANEUVERING
(TRIAL MANEUVER) Attention
Trial maneuvering is to simulate own ships course and speed in the conditions that the course and speed of a target ship are unchanged as they are. As the situation is different from any actual ship maneuvering, set values with large margins to CPA Limit and TCPA Limit. The trial maneuvering is the function of simulating own ships course and speed for collision avoidance when a dangerous target appears. When the own ship's course and speed are entered in manual mode, the trial maneuvering function checks if pre-acquired or pre-activated targets are dangerous. The ranges of course and speed to be entered manually:
Course: 360 (in 0.1 intervals)........................................................................... [EBL] dial 0 to 100 kn (in 0.1 kn steps)................................................................... [VRM] dial Speed:
5 5-56 Trial Maneuvering in the True Vector Mode In the True Vector mode, calculations are performed according to the values set by Trial Speed, Trial Course and other features, and the result is displayed as a bold-line that represents the change of own ships vector as shown in the figure below (an example of the course changed to the right). In this figure, the dangerous target forward left becomes safe as a result of simulation. The tracked target information indicates the current CPA and TCPA values regardless of the result of simulation. 5-57 5.7 Trial Maneuvering
Trial Maneuvering in the Relative Vector Mode The result of Trial maneuvering in the Relative Vector mode is shown by a change in target vector. In the figure below (in the same conditions as in the True Vector mode in the previous page), it is seen that the acquired target is a dangerous one because its vector is crossing the CPA RING. 5 The above figure shows that the relative vector of the target has changed as shown in the figure as a result of simulation (course and speed), so that the symbol color is changed into White, a safe target. Irrespective of the simulation results, the current CPA and TCPA values are shown in the tracked target information just like when the true vector mode is active. The course change of own ship is displayed as a dotted-line. Better information is provided by using relative motion and sea stabilization. 5-58 Operation of Trial Maneuvering Function Procedures 3.

Time until the start of trial maneuvering is counted down immediately after the input. The acceleration and deceleration are influenced depending on the relationship between the current speed and the input speed for trial maneuvering. If 0.0 kn/min is set for Acceleration when the speed for trial maneuvering is faster than the current speed, or for Deceleration when the speed for trial maneuvering is slower than the current speed, the system performs simulation on the assumption that the speed is changed immediately after the time set for Time to Maneuver .

For this purpose, the operator has to observe the radar displays after fully understanding the advantages and disadvantages that the radar has. For better interpretation of radar display, it is important to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships watched with the naked eyes and their echoes on the radar display. The radar is mainly used to monitor the courses of own ship and other ships in open seas, to check buoys and other nautical marks when entering a port, to measure own ships position in the coastal waters relative to the bearings and ranges of the shore or islands using a chart, and to monitor the position and movement of a heavy rain if it appears on the radar display. Various types of radar display will be explained below. RADAR WAVE WITH THE HORIZON Radar beam radiation has the nature of propagating nearly along the curved surface of the earth. The propagation varies with the property of the air layer through which the radar beam propagates. In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer than the distance to the optical horizon. The distance (D) is given by the following formula:
D=2.23(
h1 +
h2
)(nm) h1: Height (m) of radar scanner above sea level h2: Height (m) of a target above sea level Figure 6.1 is a diagram for determining the maximum detection range of a target that is limited by the curve of the earth surface in the normal propagation. 6-1 6.1 Radar Wave with the Horizon
D (nm) 6 Height of Radar Scanner Detective Range Figure 6.1 Height of Target When the height of own ships scanner is 10 m for instance,
(a) A target that can be detected at the radar range of 64 nm on the radar display is required to have a height of 660 m or more. If the height of a target is 10 m, the radar range has to be approx. 15 nm. However, the maximum radar range at which a target can be detected on the radar display depends upon the size of the target and the weather conditions, that is, the radar range may increase or decrease depending upon those conditions.
(b) 6-2 6.2 STRENGTH OF REFLECTION FROM THE TARGET The signal intensity reflected from a target depends not only on the height and size of the target but also on its material and shape. The echo intensity from a higher and larger target is not always higher in general. In particular, the echo from a coast line is affected by the geographic conditions of the coast. If the coast has a very gentle slop, the echo from a mountain of the inland appears on the radar display. Therefore, the distance to the coast line should be measured carefully. Mountain displayed on the radar display HL Sea shore line not displayed on the radar display. Figure 6.2 Table 6.1 shows the graph indicating the relation between the target detection distance and the radar reflection cross-sectional area (RCS) with regard to the type and the height of the target in a situation in which the weather is good, the sea state is calm and the radio wave propagation is normal. As revealed by this table, even on the same sea shore line, detection distance greatly differs depending on the height of the target from the surface of the sea. Furthermore, because the target detection distance is greatly influenced by the shape and material of the target and environmental conditions, such as the sea state, weather, and radio wave propagation, caution should be taken when detecting distance of target. 6-3 6.2 Strength of Reflection from the Target

Detection distance shown in the above table may greatly decrease depending on the shape of 6 6-4 6.3 SEA CLUTTER AND RAIN AND SNOW CLUTTER In addition to the echo required for observing ships and land radar video image also includes unnecessary echo, such as reflection from waves on the sea surface and reflection from rain and snow. Reflection from the sea surface is called "sea clutter," and reflection from rain and snow is called "rain and snow clutter," and those spurious waves must be eliminated by the clutter rejection function.
[I] Sea clutter Sea clutter appears as an image radiating outwardly from the center of the radar display and changing depending on the size and the shape of waves. Generally, as waves become larger, image level of the sea clutter is intensified and the clutter far away is also displayed. When waves are large and the sea clutter level is high, it is difficult to distinguish sea clutter from a small boat whose reflection intensity is weak. Accordingly, it is necessary to properly adjust the sea clutter rejection function. Table 6.2 shows the relation between the sea state (SS) showing the size of waves generated by wind and the radar's detection probability. Table 6.2 Sea state and probability of target detection RCS 0.1m2 0.5 m2 1 m2 SS1 to 2 V V V SS2 to 3 V-M V V SS3 to 4 M-NV V-M V SS4 to 5 M-NV V-M S band radar (probability to detect a target at a distance of 0.4 NM) RCS 1m2 5 m2 10 m2 SS1 to 2 V-M V V SS2 to 3 M-NV V-M V SS3 to 4 SS4 to 5 M-NV V V-M X band radar (probability to detect a target at a distance of 0.7 NM) V: Detection probability of 80 %
M: Detection probability of 50 %
NV: Detection probability of less than 50 %
6-5 6.3 Sea Clutter and Rain and Snow Clutter
As shown in Table 6.3, the number of SS increases as the wind speed becomes high and the waves become large. Table 6.2 reveals that detection probability decreases from V (80 %) to NV (less than 50 %) as the number of SS increases. Therefore, even if the sea state is calm and a target clearly appears on the radar display, when the sea state becomes rough, target detection probability decreases resulting in difficulty of target detection by the radar. Table 6.3 Relation between Douglas sea state and average wind speed and significant wave height Sea state Average wind speed (kn) Significant wave height (m) 0 1 2 3 4 5 6

<0.2 0.6 0.9 1.2 2.0 3.0 4.0 Significant wave height: an average of top N/3 higher waves when the number of waves detected within a constant time duration is N For example, in the case of a standard marine buoy, RCS of X band radar is 5 m2 as shown in Table 6.1. When observing such a target in the sea state (SS3) in which significant wave height exceeds 1.2 meters, detection probability is M-NV, as shown in Table 6.2, which indicates 50 % or less.
[II] Rain and snow clutter Rain and snow clutter is a video image that appears in a location where rain or snow is falling. The image changes according to the amount of rain (or the amount of snowfall). As precipitation increases, the image of rain and snow clutter becomes intensified on the radar display, and in the case of localized heavy rain, an image similar to the image indicating land is displayed in some cases. Furthermore, because radio waves tend to attenuate due to rain and snow, the ability to detect a target in the rain and snow clutter or a target beyond the rain and snow clutter may decrease. The amount of attenuation depends on the transmission frequency, antenna beam width, and the pulse length. Figure 6.3 and Figure 6.4 show examples in which detection distance is reduced due to the influence of precipitation. Because of this, a target, which clearly appeared up to 10 NM by an X band radar (pulse width of 0.8 s) when it was not raining, may become dimly visible up to 5 NM when the amount of rain becomes 4 millimeters per hour. Furthermore, when comparing the X band radar with the S band radar, target detection distance decreases less when an S band radar is used, which means it is influenced less by precipitation. 6-6 6 Figure 6.3 Decreased target detection distance by S band radar due to precipitation

[III] Coping with sea clutter and rain and snow clutter When the weather is bad and the ocean is rough, the use of an S band radar is effective because the radar is not influenced by sea clutter so much and attenuation due to rain drops is small. When an X band radar is used, reducing the pulse width will reduce the influence by spurious waves, and also the spurious wave rejection function effectively works; therefore, the use of short pulse is effective when the weather is bad. By using image processing functions PROC 1 to 3, it is expected that spurious waves are further suppressed. Since optimal settings for those items can be automatically made by using the function mode, it is recommended that STORM or RAIN be used by selecting the function mode when the weather is bad. For details of the function mode, see Chapter 3.9. However, these functions may make some targets invisible, particularly targets with higher speeds. 6 6-8 6.4 FALSE ECHOES The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear by the following causes that are well known:
[I] Shadow When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast. Whether there are some false echoes due to shadows can be checked monitoring the sea clutter returns, in which there may be a part of weak or no returns. Such shadows appear always in the same directions, which the operator should have in mind in radar operation.
[II] Side Lobe Effect A broken-line circular arc may appear at the same range as the main lobe of the radar beam on the radar display. This type of false echo can easily be discriminated when a target echo appears isolated. (See Figure 6.5) Figure 6.5
[III] False Echo by Secondary Reflection When a target exists near own ship, two echoes from the single target may appear on the radar display. One of those echoes is the direct echo return from the target and the other is the secondary reflection return from a mast or funnel that stands in the same direction as shown in Figure 6.6. Figure 6.6 6-9 6.4 False Echoes
[IV] False Echo by Multiple Reflection When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.7, multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target.
[V] Second Time Echoes Figure 6.7 The maximum radar detection range depends upon the height of the scanner and the height of a target as described in the section of The Horizon for Radar Beam Radiation. If a so-called duct occurs on the sea surface due to a certain weather condition, however, the radar beam may propagate to a abnormally long distance, at which a target may be detected by the radar. For instance, assuming that the pulse length is MP3 (on the repetition frequency of 1400 Hz), the first pulse is reflected from a target at about 58 NM or more and received during the next pulse repetition time. In this case, a false echo (second time echo) appears at a position that is about 58 NM shorter than the actual distance. If the false echo appears at 5 NM on the radar display, the true distance of the target is 5+58=63 NM. On the pulse length is SP1 (on the repetition frequency of 2250 Hz), a false echo may appear at a position that is about 36 NM shorter than the actual distance. This type of false echo can be discriminated by changing over the range scale (the repetition frequency), because the distance of the target changes accordingly. If second time echo is appeared, the use of Economy mode in PRF menu is effective. Otherwise, Stagger Trigger menu set to on. (See section 3.8.3) 6 6-10
[VI] Radar Interference When another radar equipment using the same frequency band as that on own ship is near own ship, a radar interference pattern may appear on the radar display. This interference pattern consists of a number of spots which appear in various forms. In many cases, these spots do not always appear at the same places, so that they can be discriminated from the target echoes. (See Figure 6.8) Figure 6.8 If radar equipment causing an interference pattern and this radar are of the same model, their transmitting repetition frequency is nearly the same. As a result, interference patterns may be displayed concentrically. In this case, the interference patterns cannot be eliminated by using only the interference reflector function, so press [TX/PRF] key several times to fine-tune the transmitting repetition frequency. An interference suppressing effect can be heightened by applying a different transmitting repetition frequency to the interference pattern source radar and this radar. 6-11 6.5 Display of Radar Transponder

The SART is designed to operate in the 9 GHz frequency band. When receiving the 9 GHz radar signal (interrogating signal) transmitted from the radar equipment on a rescue ship or search aircraft, the SART transmit a series of response signals to inform the distress position to the rescue and search party.
* This radar provides a shortcut item to make settings for SART signal reception. Execution of this item automatically switches to the setting for SART reception. It also functions for detect the beacon or target enhancer. NM or 12 NM.

Attention
When the SART function is set to ON, small targets around own ship will disappear from the radar display. So it is necessary to exercise full surveillance over the conditions around own ship by visual watch in order to avoid any collision or stranding. If two or more sets of radar equipment are installed on own ship, use one set of 9 GHz band radar for detection of the SART signal and operate others as normal radars for avoiding collision, monitoring targets around own ship, and checking on own ships position and avoidance of stranding. After end of detecting the START signal, turn the START display off. Then the radar returns normally to the nautical mode. 6-13 SECTION 7 SETTINGS FOR SYSTEM OPERATION 7.1 SETTINGS AT INSTALLATION................................................................7-1 7.2 SETTINGS ..............................................................................................7-10 7.3 ADJUSTMENT........................................................................................7-22 7.4 MAINTENANCE MENU..........................................................................7-30 7.1 SETTINGS AT INSTALLATION CAUTION This section describes the electrical adjustment procedures to be performed by service engineers during system installation.
